JSON To Features Tool : Error 000206

I'm attempting to use the 10.2 JSON to Features Tool from Desktop. I'm getting the following error:

DescriptionThe named feature class cannot be created as named.

SolutionThe name that has been specified is likely invalid. Correct the name and try again. All data formats have characters that are considered invalid and should not be used as feature class names. Rename the feature class using characters that are valid for the underlying database. In addition to spaces, the following list contains characters that should not be used in a geodatabase feature class name: `~@#$%^&*()-+|\,<>?{}.!'[]:;. If working in Python, ArcPy has functions that allow you to validate table names and field names. You can use the ValidateTableName or ValidateFieldName functions to ensure that the name is valid.

I have tried removing the Shape.Area and Shape.Len fields, but I receive the same error. Any help is appreciated.
